Biology
Name: ________________________
Date: ___________ Period: _______
Objective: In this activity, you will use the following web pages to examine the processes of mitosis and
meiosis. Both of these processes are important in homeostasis as well as human reproduction.
PART A: Cell Growth and Mitosis

5. Why are cells limited in size? ___________________________________________________________
6. Click on the animation. A cell with 2cm sides has what surface area? ______What volume? _________
7. What would be the surface to volume ratio? _______________________________________________
8. A cell with a large volume will have a more difficult time doing what? __________________________
Click on the tab, “What Does Mitosis Do?”
9. What are the 2 major functions of mitosis? ________________________________________________
Click on the tab, “Built-in Controls in Mitosis”
10. What are the 2 ways that cells “know” to stop dividing? ______________________________________
Please go to the following webpage: https://www2.estrellamountain.edu/faculty/farabee/BIOBK/BioBookmito.html
11. What ends the cell division process where one cell splits from the sister cell? _____________________
12. Some cells divide rapidly. Example? ______________
Some cells do not divide at all after maturity. Example? _______________________
13. What is the result of binary fission (genetically the same or different)? _________________________
14. What is the genetic relationship between resulting cells in mitosis (genetically the same or different)?

15. Label the following steps of mitosis:
PART B: Meiosis

16. Why is the meiosis important? _____________________________________________________
17. Start the animation. What do the chromosomes do in Prophase 1? ___________________________
18. Compare how chromosomes line up on the equator (for separation) in Metaphase 1 and 2?
_________________________________________________________________________________
